I went to a wedding in one this last summer, and on the church calender of events board they listed three weekly Yoga Workshops in the church and a weekly Buddhism class.
I think it's pretty stupid for a Christian Church to do a Fred Phelps and burn a Quran. They have the right to do it, but it's just plain dumb. But for a church that claims to be Christian to teach from the Quran is sacrilegious.
